How to call an executable file with parameters from powershell script

Question

I am looking for help on how to call cmd with specific parameters from a powershell script. So far I have written below, but it gives me an error message saying that $ _cmd is not recognized.

I am trying to pass the date and date to exe ... From today, as you can see, it should be today - 1, and today it should be now. The executable path is D: \ DataService and therefore I set the path at the beginning of the script.

    Write-Host "Get data from service"

$path ="D:\DataService"

Push-Location $path
$Date = Get-Date
$DateFrom = $Date.ToString("yyyy-MM-dd HH:mm:ss")
$DateTo = $Date.AddDays(-1).ToString("yyyy-MM-dd")
$_cmd = "ReportGen.exe -ReportType Data -DateFrom $DateFrom $DateTo"

%$_cmd%

Any suggestions please?

Answer 1

Do not create a command line. Just use the call statement ( &):

Write-Host 'Get data from service'

$path = 'D:\DataService'

Push-Location $path

$Date     = Get-Date
$DateFrom = $Date.ToString('yyyy-MM-dd HH:mm:ss')
$DateTo   = $Date.AddDays(-1).ToString('yyyy-MM-dd')

& ReportGen.exe -ReportType Data -DateFrom $DateFrom $DateTo
